I bicycled alone, self supporting from Seattle, WA to Oakland, CA this summer so I biked a lot of Highway One. One of the many things that happens when you are doing this is, you start to meet other people traveling Hwy 1 on their own power and you naturally take an interest in each other.
This past weekend driving it to Big Sur, CA. I saw three touring bicyclists. I waved.
Then I saw a young couple with backpacks. I wondered if they were walking between towns which would have been strange enough or if they were hiking Hwy 1 as I’d met a few people doing that. I noticed the guy was walking in his socks and immediately decided they were doing the highway itself. People who walk the coastline highway are even crazier than those who bike it.
